Cage-Free Pullets Minimally Affected by Stocking Density Stressors [PDF]

Animals
Management choices during the pullet phase can affect behavior, welfare, and health later in life, but few studies have evaluated the pullet phase, particularly in extensive housing systems.

Fecal microbiome analysis uncovers hidden stress effects of low stocking density on rainbow trout [PDF]

Animal Microbiome
Background Recirculating aquaculture systems can cause chronic stress in fish when stocking density is too high. However, this study tested whether low stocking density can cause fish stress.

Effect of Stocking Density on Behavioural and Physiological Traits of Laying Hens [PDF]

Animals
This study analysed stocking density as a major stress factor for laying hens and assessed its impact on selected behavioural and physiological traits of the birds. The study population included 142 birds of the Green-legged Partridge breed (12 males and

Stocking density-induced changes in growth performance, blood parameters, meat quality traits, and welfare of broiler chickens reared under semi-arid subtropical conditions.

PLoS ONE, 2022
Broiler production in semi-arid tropics must contend with high levels of heat stress, which have implications on stocking density, bird welfare, and profitability.
